First installed shots of the RKP F8x M3/M4 Diffuser
Today, RKP is proud to announce our first entry into what will be an extensive F8x M3/M4 catalog.
While the majority of the F8x M car is stunningly muscular, the diffuser section in particular leaves something to be desired. The flat polyurethane insert installed from BMW does not match the M3/4’s aerodynamically sculpted exterior, and so was the first item RKP elected to attack. In contrast, the RKP diffuser was designed with full length fins that reach all the way from the inside of the insert to their termination point at the rear of the bumper. The fins are particularly thin, and although this makes them especially difficult to manufacture, their athletic appearance is more purposeful and athletic. Unlike the BMW performance diffuser, RKP’s fins extend all the way to the edge of the diffuser, giving them a much more noticeable look in all of the right areas. The RKP M3/4 diffuser has been in development for over 3 months with a specific focus on fit and finish. After several revisions, we have carefully sculpted what we believe to be a truly perfect fitting part. This was no easy feat, as working with the complex rear bumper shape and creating a component that would be durable, strong, lightweight, and integrate perfectly with the original BMW mounting took special care and attention to detail. We are proud to say that this diffuser fits like all other RKP components- absolutely flawlessly. Carbon Weave Options:

This one with more aggressive looking fins looks much better than BMW Performance parts.
Is opening area of the diffuser (where tips come in) exactly same size as stock one? I am asking this because my exhaust has huge tips (102mm). If opening is smaller than stock diffuser, I will have some issues. |

Have you tested this diffuser to see if the trunk release works installed? apparently the BMW Perf version dissables the motion sensor trunk release.
Looks great, btw!

Just like the OEM M-performance diffuser the "foot swipe" function will not work with any carbon diffuser on the M3/4 market just like the F10 M5.
